本研究分兩部分，第一部分主要探討以水熱法(hydrothermal method)成長錫酸鋅奈米粒與以兩步驟法成長錫酸鋅奈米粒/氧化鋅奈米線複合材料。藉由檸檬酸鈉的添加與反應溫度的改變，可改變錫酸鋅奈米顆粒的大小。以兩步驟法成長錫酸鋅奈米粒/氧化鋅奈米線複合材料的部分，先以化學浴沉積法(chemical bath　deposition)成長氧化鋅奈米線陣列於氧化銦錫(Indium Tin Oxide)基板上，再以此氧化鋅奈米線陣列為基板利用水熱(Hydrothermal method)成長錫酸鋅奈米粒於奈米線陣列間隙中。探討不同反應物濃度、反應溫度、反應壓力、檸檬酸鈉的添加與濃度以及支撐物對成長錫酸鋅奈米粒於氧化鋅奈米線陣列間隙的影響。
第二部分為以電紡絲法合成鋅錫氧化物奈米纖維作為染料敏化太陽能電池散射層之用途。探討了溶液種類、電壓、工作距離以及溶液流速等變因，以找出電紡絲之纖維膜密度最高且纖維直徑最小之參數。以XRD檢測為ZnO、SnO2、Zn2SnO4混和而成之鋅錫氧化物奈米纖維膜。將此奈米纖維膜應用在氧化鋅奈米線與二氧化鈦奈米線染料敏化太陽能電池之散射層，並進一步以甲醇蒸氣的處理之，由量測電池的特性可知散射層之添加可使得光電流及效率有不同程度的提升。

Synthesis of Zn2SnO4 nanoparticles(NPs) has been conducted using hydrothermal method. The particle size is tunable by the addition of sodium citrate and change of temperature. Zn2SnO4 NP/ZnO nanowire (NW) composite are further fabricated by a two-step method. ZnO NW array is first grown on ITO substrate using chemical bath deposition method. The Zn2SnO4 NPs are formed in the intensities of ZnO NW array by hydrothermal method. The effects of reactant concentration, temperature, pressure, the addition of sodium citrate and the susceptor material on the formation of Zn2SnO4 NPs are investigated in this study. Zinc/Tin Oxide nanofibers are further synthesized using electrospinning method. The Effects of tin source, voltage, distance between injector and substrate and flow rate on the density and diameter of the nanofibers are examined for obtaining a high-density nanofiber film. Using the nanofiber film as the light scatter layer of the NW dye-sensitized solar cell(DSSC),the short-circuit current and efficiency of the NW DSSC is enhanced.
